Yes, as I said, that test isn't the one your code is failing it is this one:

Test.assertEquals(pigIt('O tempora o mores !'),'Oay emporatay oay oresmay !')

If you print the input you'll see that.

You're using the wrong input value there, it should be 'O tempora o mores !'

Leave punctuation marks untouched.

So !ay is wrong.

If you travel down, you subtract button from level. So a test of goto(1, "0") == -1.
